Exercise gives a short, real attention boost — it isn't a treatment
A meta-analysis of exercise trials in children with ADHD found small-to-moderate improvements in attention and inhibition after activity.
The short version
Meta-analysis · kids + teens · 2015
Randomised trials measured attention and inhibition in children with ADHD after bouts of exercise.
Improvements were small to moderate and clearest immediately after activity.
Studies were small and measures inconsistent.
What they studied
- Randomised controlled trials of physical exercise interventions in school-aged children with ADHD were pooled.
- Outcomes included attention, inhibition, hyperactivity and impulsivity measured shortly after exercise sessions.
What they found
- Small-to-moderate improvements in attention and inhibition following aerobic exercise.
- Effects were most consistent for acute single sessions rather than long-term programmes.
Why it matters
- Moving before the hard thing is a legitimate, free, immediate lever — especially for kids before homework.
- It gives a reason to protect break time rather than remove it as a consequence.
What it doesn't mean
- Effects are short-lived; this is not a substitute for evidence-based treatment.
- The included studies were small with varied measures.
- This is children's research; do not read it straight across to adults.
The bigger picture
Moderate, with real methodological limits. Nobody serious claims exercise treats ADHD; plenty of evidence says it helps the next hour.

Why Does My Brain Notice Everything?
The hum of the lights, a pencil tapping two rows over, the smell of lunch through the door — some brains notice all of it, all at once. Here's why, and what actually helps.
